Air Fuel Ratio Sensor
INSPECTIONINSPECT HEATER RESISTANCE OF A/F SENSORS
a. Disconnect the A/F sensor connector.
b. Using an Ohmmeter measure the resistance between terminals +B and HT.
Resistance: 0.8 - 1.4 Ohm at 20 °C (68 °F)
If the resistance is not as specified, replace the sensor.
Torque: 44 N.m (440 kgf.cm, 31 ft.lbf)
c. Reconnect the A/F sensor connector.
